The ACE9000 SSP PLC is a type of prepaid meter that uses a secure system to distribute electricity. The meter displays error codes to indicate faults or problems with the meter. Here are some of the error codes that may be displayed on the ACE9000 SSP PLC:
ACE9000 SSP PLC Error Codes:
OOOOO – Old token: Token received is older than the oldest token on the TID stack.
UUUUU – Used token: Token received is already present on the TID stack.
XXXXX – Key expired: Token received whose TID (highest byte) is greater than the KEN value.
DDDDD – Default key: Credit tokens are rejected with this message when the meter has a Default key (DDTK).
EEEEE 02 – NVM failure: One or more of the secure stores are invalid.
EEEEE 04 – Overflow error: Token cannot be accepted because it causes an overflow. This token can be accepted at a latter point in time when an overflow will not occur.2(^63Wh)
EEEEE 05 – Key type error: Key type not supported. This is displayed when an attempt is made to change the key to DCTK.
EEEEE 06 – Format error: Format error
EEEEE 07 – Range error: Range error (If Key Revision number or Tariff index are illegal values in a Key Change Token)
EEEEE 08 – Function error: The function is not supported (disabled/invalid).
EEEEE 13 – CRC error: The token’s CRC does not match the calculated CRC.
EEEEE 14 – Manufacturing Code error: The token is not valid because the Manufacturing Code in the token is not the Itron Manufacturing Code.
EEEEE 20 – Comms Error: Automatic update request failure – communications
EEEEE 21 – Comms Error: User request failure – communications
EEEEE 92 – CIU NVM CIU: Non Volatile Memory Corruption
EEEEE 98 – CIU Short Code: CIU short code rejection (invalid CIU 4 digit short code)
EEEEE 99 – CIU decode fail: CIU failed to decode MCU packets
- EEEEE 01: NVM failure. This means that one or more of the secure stores are invalid.
- EEEEE 02: CRC error. This means that the token’s CRC does not match the calculated CRC.
- EEEEE 03: Key type error. This means that the key entered into the meter is not of a supported type.
- EEEEE 04: Key is expired. This means that the key entered into the meter has expired.
- EEEEE 05: Function error. This means that the function requested is not supported by the meter.
- EEEEE 06: Used token. This means that the token entered into the meter is already present on the TID stack.
- EEEEE 07: Key not found. This means that the key entered into the meter is not found in the meter’s database.
- EEEEE 08: TID overflow. This means that the TID stack is full and no more tokens can be added.
- EEEEE 09: Credit overflow. This means that the credit balance on the meter has exceeded the maximum allowed value.
- EEEEE 10: Tamper error. This means that the meter has been tampered with.
- EEEEE 11: Communication error. This means that the meter is not communicating properly with the power grid.
If you see any of these error codes on your ACE9000 SSP PLC, you should contact your power utility company immediately. They will be able to send a technician to investigate the problem and repair the meter if necessary.
Here are some additional tips for troubleshooting ACE9000 SSP PLC error codes:
- Make sure that your appliances are turned off and that there are no loose connections in the electrical wiring.
- If you have recently installed a new appliance, check the appliance’s power rating to make sure that it is not overloading the circuit.
- If you have recently experienced a power outage, check the meter to make sure that it is not damaged.
If you have checked all of the above and the error code is still displayed, you should contact your power utility company for assistance.
